I'm about to start with my first niche (not really original niches, but it's just to start and get some experience.

Now I made a (fake) hack and I want to make some video's about for Youtube, now I need a free (can be cracked) recording software that doesn't give your pc too much lagg. I used to use Fraps, but it can only record games in some way... Can anyone help me with this?
I searched a little bit on the forum, but couldn't really find something (maybe searched or looked too bad, not sure about that though)
